vigil-llm alternative llm-guardBoth llm-guard and vigil-llm are security tools designed to protect against potential threats in Large Language Model interactions, such as prompt injection attacks.
Shared compatibility
- Python · vigil-llm: Python runtime · llm-guard: Python runtime
Choose vigil-llm if…
- License: vigil-llm is Apache-2.0, llm-guard is MIT.
- Requirements: - Vigil supports local embeddings via sentence-transformers and can integrate with OpenAI's models.; - It is built as a Python library but also provides a REST API for more flexible integration..
- Both llm-guard and vigil-llm are security tools designed to protect against potential threats in Large Language Model interactions, such as prompt injection attacks.
- Tags unique to vigil-llm: adversarial-attacks, yara-scanner, llm-security.
- vigil-llm ships Docker support for self-hosted deployment.
- - When you need to detect prompt injections or jailbreaks in the inputs of LLM applications.
When NOT to use vigil-llm
- - If your project requires a stable, fully vetted solution given Vigil's current alpha stage status.
- - For production use cases that demand a more comprehensive and proven AI firewall technology over experimental tools.
Choose llm-guard if…
- License: llm-guard is MIT, vigil-llm is Apache-2.0.
- Both llm-guard and vigil-llm are security tools designed to protect against potential threats in Large Language Model interactions, such as prompt injection attacks.
- Tags unique to llm-guard: llmops, large-language-models, adversarial-machine-learning, chatgpt.
- Also covers LLM Frameworks.
When NOT to use llm-guard
- Last GitHub push was 206 days ago (slowing maintenance, Dec 15, 2025). Validate activity before betting a new project on llm-guard.
- Evaluation & Observability: Defer heavyweight eval infra only until you have real traffic - never skip it once users depend on answers.
- LLM Frameworks: Avoid a framework for a single prompt-and-retrieve call; the abstraction can cost more than it saves.
